Usage Guideline
When traffic segmentation forwarding domain is specified, packets received by the port will be
restricted in Layer 2 packet forwarding to interfaces within the domain. When the forwarding domain
of a port is empty, Layer 2 forwarding for packets received by the port is not restricted.
The traffic-segmentation forward command can be entered multiple times. The following interfaces
will be appended into the forwarding domain. Use the no form command will remove the specified
interface from the traffic segmentation forward member list.
The traffic segmentation member list can be comprised of different interface types, for example port
and port-channel in the same forwarding domain. If the interfaces specified by the command include a
port-channel, all the member ports of this port-channel will be included in the forwarding domain.
If the forwarding domain of an interface is empty, then there is no restriction on Layer 2 forwarding of
packets received by the port.
Example
This example shows how to configure traffic segmentation. It restricts the flooding domain of eth3/0/1
to a set of ports, which are eth4/0/1 – eth4/0/6.
Switch# configure terminal
Switch(config)# interface eth3/0/1
Switch(config-if)# traffic-segmentation forward interface range eth4/0/1-6
Switch(config-if)#
